Abstract: 1,148,963. Pick-up arms. H. MATSUSHITA. 30 Jan., 1967 [29 Jan., 1966], No. 4500/67. Heading G5R. A pick-up arm includes two pivotallyconnected links of the same effective length and a pair of coupled pulleys, or the like, of unequal size associated with each link, the centres of each pair being spaced by a distance equal to the above-mentioned effective length; the smaller ones of each pair are concentrically and coaxially positioned with the pivotal connection, and each link is fixed to the smaller one of the pair of pulleys associated with the other link; in each pair, the ratio of pulley diameters is 2:1; with the larger pulley associated with the first link fixed, the links are thus geared together for movement of the larger pulley associated with the second link along a straight line without change in its orientation. As shown in Figs. 4 and 5, pulley 6 associated with link 1 is fixed, and pulley 7 associated with the same link is secured to link 9. Pulley 12 associated with link 9 swivels about a pivot 10, while pulley 13 associated with the same link is secured at 3 to link 1. An endless belt 8 or 14 encircles the two pulleys of a pair. A lever 22, Fig. 4, pivoted at 21, Fig. 5, to the lower end of pulley 12 is provided with a cartridge 24 and counterweight 25. The dotted line through the disc record centre shows the path of the stylus. Variants of this embodiment are as follows: counterweighting may be assisted by an adjustable tension spring above the cartridge lever between cartridge and pivot; the movement of links 1 and 9 may take place to the left of the pivot 3; the lever 22 may be omitted, and the mounting 16 located so that pivots 10, 3 and 2 are in a line, radial to the disc record, in fully-extended position. In Fig. 8, a cantilever support 28 is provided so that the links may be shorter, and the construction is such that pivot 10 may pass under pivot 2 to permit movement on both sides of the support. Fig. 14 shows the construction of a support pillar for a more elaborate form of Figs. 4 and 5. The fixed pulley 36 (corresponding to 6) may be raised and lowered by rotating an adjusting ring 53 having threaded engagement with the downwardly-extending support 47 integral with the pulley; it may be pivoted by a handle 67 which moves a collar 54 from which a bolt 69 extends through a slot 62 into a longitudinal groove 68 in support 47. The slot 62 is provided in an annulus upstanding from an adjustable base 55 secured to a fixed base 56 by bolts 61 and nuts 70.

Title: Device for fastening flexible printing plates on the forme cylinder of a printing machine
Inventor: BASISTA MANFRED
IPC: B41F27/12
Filed: 1965-02-03
Abstract: 1,069,011. Printing plates. PLAMAG PLAUENER DRUCKMASCHINENWERK VEB. Feb. 3, 1965, No. 4691/65. Heading B6C. Clamping and tensioning of a flexible printing plate 35 on a printing cylinder 1 are .effected by members slidable axially in a longitudinal groove 2 within the cylinder. These members include clamping bars 13, 14 each of which is axially slidable within a channel member 10 or 11. Each channel member 10 or 11 is movably retained within a member 3 or 4 within the groove and is connected to a member 24 mounted on and slidable axially of the cylinder by a rod which is fixed to the member 24 and pivotally mounted on the member 10 or 11. Each member 10 or 11, which carries wedge surfaces 18, 19, on its inner upright surfaces for co-operation with wedge surfaces 20, 21 on the associated clamping bar 13 or 14, is threndedly connected to the member 24 by rods 32 which pass through holes in a disc 22. This disc is rigidly fixed to the cylinder 1 and mounts the member 24 by means such that rotation of a spindle 27 mounted on the disc effects movement of the member 24 axially of the cylinder. The ends 36, 37 of the plate are held between the inner walls 12 of the channel members 10 and 11 and an upper portion 16 of associated clamping members 13 or 14. Rotation of the rods 32 effects axial movement of the clamping members 13 and 14 and thus moves the upper portions 16 towards or away from the walls 16 thereby clamping or releasing the plate ends. Tensioning is effected by moving the units consisting of the members 10 and 11 with their associated members 13 and 14 transversely of the cylinder. This is achieved through axially movable tensioning members 8 and 9 which are located within the members 3 and 4 in the groove 2 and co-operate with wedge surfaces 5 carried by wedge strips 6, 7 lining the groove formed by the members 3 and 4. The plane surfaces of the members 8 and 9 contact the outer walls of the channel members 10 and 11. The members 8 and 9 are screw-threadedly connected through rods 31 to the disc 22 and when moved to the right as viewed in Fig. 1 through appropriate rotation of the rods 31 cause the channel members 10 and 11 to move towards each other thereby tensioning the plate 35 around the cylinder. For circumferential adjustment of the plate 35 the appropriate tension member 8, 9 is slacked-off by actuation of the pertinent rod 31 and at the same time the other member is tightened. For axial plate adjustment both tension members 8, 9 are slackened and then the member 24 is moved axially the required amount through appropriate rotation of the spindle 27. The plate is finally re-tensioned by tightening the members 8 and 9. With two printing plates side-by-side on the cylinder the arrangements of Fig. 1 may be provided at each end of the cylinder.

Title: Improvements in Wire Stitching Machines.
Inventor: NASMITH JOHN WILLIAM
IPC: B27F7/21
Filed: 1918-03-18
Abstract: 119,816. Nasmith, J. W. March 18, 1918. Stapling and discontinuous wire-stitching.-A wire-stitching machine is provided with means whereby an adjustment of the work support automatically adjusts the feed and cut-off in proportion for proper clinching, with means to cause the driver to dwell while clinching takes place, and with an improved gripper to prevent the wire from falling out of the nick or slot in the stapleforming anvil. A block B, Fig. 1, has mounted to slide on it a work support A, and is formed with an extension B', which has a projecting head I inclined at 45 degrees and engaging a groove in a sliding bar 4 secured to a bracket T pinned to a plate P carrying the cut-off mechanism. By loosening a clamping handle H and screw 6, the work support may be lowered by means of a hand-lever L and the plate P correspondingly adjusted. The usual wire feed gripper G is actuated through a link 7 from a spring-controlled lever V pivoted at 8 and actuated from a cam M. The upper part of this lever is exactly half the length of the lower part, which, at its centre, carries a steel point 0 adapted to engage a set-screw 9 adjustably carried by the bracket T. With this arrangement, an adjustment of the cut-off will result in the feed being increased by double the amount of the displacement of the knife, ta supply the exact addition to each leg of the staple. In a modified construction, Fig. 3, the extension B<1> carries a slotted bracket 17 engaged by a pin 15 extending from a lever 14 secured to one end of a shaft 11; at the other end of this shaft and at right-angles to the lever 14 is secured a second lever 12 in engagement with a pin 13 which serves also as the clamping-screw 6 for the plate P. The lever V is in two parts V, V<1>, the upper part V<1> being rocked about the pin 8 by an eccentric Wand actuating the lower part through a set-screw V' as in the prior construction ; a spring 10 returns the lower part V to an extent limited by the stop O and set screw 9. To provide for a dwell of the staple-driver 22, Fig. 3, during clinching, a slotted head 20, which is secured to the stapledriver and receives a roll 19 on a pin 18 secured to the actuating cam C, is formed with a shallow depression 23 in the lower face of its slot. This depression is an arc of a circle of the same radius as that described by the pin 18, which enters the depression when the driver is at the bottom of its stroke. The gripper for holding the cut-off length of wire in the slot in the staple-forming anvil 38, Fig. 4, comprises a spring-pressed blade 33 pivoted in a slot 24a in the usual staple supporter 24, which projects through the forked lower end of the staple former 31. The staple supporter and gripper are pushed aside by the driver 22 as it descends to drive the staple, but before the driver, as it ascends again, clears the anvil, the gripper is forced by its spring through a slit in the lower end of the driver into operative engagement with the anvil.
